x 3 Claims. (01. 219-39) This invention relates to improvements incomsupplied to the heating element, a thermostat, bined fans and heatersand has for one of its obconventionally indicated at I4, may beintroduced jects to provide a simple and practical device in between thecoil of said heating element and which a heater and fan are assembled ina manswitch I i.
